Definitions

  • the invention relates to a method for producing an inner automotive structural part of the type comprising an inner upper front pillar, an inner center pillar and an inner side rail extending between the inner upper front pillar and an upper end of the inner center pillar, said method comprising the steps of:
  • the invention also relates to a method for producing an automotive structural part with such an inner automotive structural part.
  • Such an inner automotive structural part which forms the upper door ring part of an automotive vehicle has to have particular mechanical properties in order to be able to protect the passengers of the automotive vehicle against intrusions of any kind inside the passenger compartment.
  • the upper door ring part is more particularly arranged to prevent the intrusion of the roof of the vehicle in the passenger compartment, or roof crush, in case of a rollover accident.
  • the reinforcement elements are, for example, attached to parts of the center pillar and of the upper front pillar in the form of patches having a complementary shape of the part of the center pillar and of the upper front pillar to which the reinforcement elements have to be attached.
  • the reinforcement element therefore has to be put into shape; for example during a cold stamping step and then be attached to the complementary area of the pillar that has to be reinforced.
  • the small dimensions of the reinforcement element make it hard to manipulate through the stamping process and through the attaching step.
  • the production of the reinforced structural part is therefore not optimized.
  • Another solution would be to directly provide a reinforced blank, having a localized thicker area in the area to be reinforced, and then to shape the blank into the pillar.
  • One of the objects of the invention is to overcome these problems by providing a method for producing a reinforced structural part that can be implemented in a simple manner and which can be easily adapted to several vehicle models.
  • the present invention provides a method of the afore-mentioned type, wherein the method comprises, prior the hot stamping steps, the steps of:
  • Attaching the reinforcement blank to the pillar part prior the hot stamping step avoids having to manipulate a small part through the hot stamping steps since the reinforcement blanks are hot stamped together with the pillar blanks, which are easier to handle. Furthermore, the reinforcement properties can be modified easily simply by modifying the properties of the reinforcement blanks, without having to modify the pillar blanks. Consequently, the same pillar blanks can be used for various automotive vehicle models having different reinforcement requirements.
  • vehicle underbody structure comprises one or more of the following features, considered alone or according to any technically possible combination:
  • the outer automotive structural part has a concave cross-section, the inner automotive structural part being arranged to close the cavity of the outer automotive structural part.
  • FIG. 1 is a front view of an inner automotive structural part obtained by a method according to the invention
  • FIG. 2 is a perspective exploded view of the inner structural part of the FIG. 1 .
  • FIG. 3 is a front view of the blanks used in the method according to the invention.
  • the invention relates to a method for producing an inner automotive structural part 1 comprising an inner upper front pillar 2 , an inner center pillar 4 and an inner side rail 6 .
  • Such an inner automotive structural part 1 is intended to form, with a complementary outer automotive structural part, an automotive structural part forming the upper part of a door ring arranged to surround and receive a front door of an automotive vehicle.
  • inner and outer are defined relative to the interior and to the exterior of an automotive vehicle. “Inner” defines what is turned toward the interior of the vehicle and “outer” defines what is turned toward the exterior of the vehicle.
  • the terms “lower” and “upper” are defined relative to the elevation direction of an automotive vehicle in regular use condition.
  • the upper front pillar extends in the elevation direction of the vehicle and is intended to be attached to the lower front pillar to form the front pillar of the vehicle, also known as the A-pillar.
  • the center pillar also known as the B-pillar, extends in the elevation direction of the vehicle and is intended to receive the locking means of a door of the vehicle and to extend between the front door and the rear door in the case of a five doors vehicle.
  • the center pillar extends substantially along the whole height of the passenger compartment.
  • the side rail extends in the rear-front direction of the vehicle, or longitudinal direction, between a front longitudinal end 8 and a rear longitudinal end 10 .
  • the side rail joins the upper front pillar and the center pillar and is intended to support the roof panel of the vehicle.
  • the inner upper front pillar 2 and the inner side rail 6 are for example made of a single part and the upper end 12 of the inner center pillar 4 is attached to the inner side rail 6 , for example to a central part 14 of the inner side rail 6 .
  • the central part 14 extends between the front longitudinal end 8 and the rear longitudinal end 10 .
  • the inner side rail 6 can extend substantially along the whole length of the passenger compartment such that the rear longitudinal end 10 is attached to a rear pillar of the vehicle (not shown).
  • the inner center pillar 4 can be attached to the rear longitudinal end 10 of the inner side rail 6 .
  • the inner upper front pillar 2 , the inner side rail 6 and the inner center pillar are made of a press hardened steel part having a tensile strength greater than 1200 MPa, for example greater than 1300 MPa.
  • the press hardened steel part presents a martensitic structure. Such high mechanical characteristics make it a suitable part for forming a reinforcement structure such as the door ring.
  • composition of such steel may comprise for example, in % weight: 0.15% ⁇ C ⁇ 0.5%, 0.5% ⁇ Mn ⁇ 3%, 0.1% ⁇ Si ⁇ 1%, 0.005% ⁇ Cr ⁇ 1%, Ti ⁇ 0.2%, Al ⁇ 0.1%, S ⁇ 0.05%, P ⁇ 0.1%, B ⁇ 0.010%, the remainder being iron and unavoidable impurities resulting from the elaboration.
  • the steel composition comprises for example, in % weight: 0.20% ⁇ C ⁇ 0.25%, 1.1% ⁇ Mn ⁇ 1.4%, 0.15% ⁇ Si ⁇ 0.35%, ⁇ Cr ⁇ 0.30%, 0.020% ⁇ Ti ⁇ 0.060%, 0.020% ⁇ Al ⁇ 0.060%, S ⁇ 0.005%, P ⁇ 0.025%, 0.002% ⁇ B ⁇ 0.004%, the remainder being iron and unavoidable impurities resulting from the elaboration.
  • the tensile strength of the press hardened part is comprised between 1300 and 1650 MPa.
  • the steel composition comprises for example, in % weight: 0.24% ⁇ C ⁇ 0.38%, 0.40% ⁇ Mn ⁇ 3%, 0.10% ⁇ Si ⁇ 0.70%, 0.015% ⁇ Al ⁇ 0.070%, Cr ⁇ 2%, 0.25% ⁇ Ni ⁇ 2%, 0.015% ⁇ Ti ⁇ 0.10%, Nb ⁇ 0.060%, 0.0005% ⁇ B ⁇ 0.0040%, 0.003% ⁇ N ⁇ 0.010%, S ⁇ 0.005%, P ⁇ 0.025%, %, the remainder being iron and unavoidable impurities resulting from the elaboration.
  • the tensile strength of the press hardened part is higher than 1800 MPa.
  • the steel may be uncoated or coated, for example galvannealed or galvanized by any suitable process such as hot dip coating, electrodeposition, vacuum coating.
  • the inner upper front pillar 2 and the inner center pillar 4 each comprise a localized reinforced area 16 and 18 .
  • the reinforced areas 16 and 18 present an increased thickness, which is greater than the thickness of the rest of the pillars, i.e. the thickness of the pillars outside the reinforced areas 16 and 18 .
  • the inner upper front pillar 2 and the inner center pillar present a thickness substantially comprised between 0.7 and 1.5 mm outside the reinforced areas 16 and 18 and a thickness substantially comprised between 1.2 and 3 mm in the reinforced areas 16 and 18 .
  • the reinforcement areas 16 and 18 do not extend over the whole surface of the inner upper front pillar 2 and the inner center pillar 4 .
  • the reinforced area 16 of the inner upper front pillar 2 extends in the upper end of the inner upper front pillar 2 , i.e. at the junction between the inner upper front pillar 2 and the inner side rail 6 .
  • the reinforced area 18 of the inner center pillar 4 extends in a central area of the central pillar, i.e. in an area spaced from the lower end and the upper end 12 of the inner central pillar 4 . More particularly, in a mounted vehicle with the door closed, the reinforced areas 16 and 18 extend substantially opposite the base of the window of the front door of the vehicle, on either side of said window. Consequently, the reinforced areas 16 and 18 extend substantially at the same height in the elevation direction of the vehicle.
  • Such localized reinforced areas allow the door rings of the vehicle to sustain a rollover accident without the roof penetrating in the passenger compartment, while allowing the major part of the door ring to have a reduced thickness, corresponding to the thickness of the pillar outside the reinforced areas. Consequently, the automotive structural part can be light while having satisfactory mechanical properties.
  • this inner upper front pillar blank 20 comprises a part forming an inner side rail blank for forming the inner side rail 6 .
  • the inner upper front pillar blank 20 and the inner side rail blank are formed of a single blank.
  • the blank 20 is substantially planar and is for example cut from a steel sheet to have the appropriate contour and dimensions to form the inner front pillar and side rail after hot stamping.
  • the steel sheet has a structure consisting essentially of ferrite and perlite arranged such that the inner upper front pillar and side rail will have a structure consisting of 95% or more of martensite after hot stamping.
  • the thickness of the blank 20 is equal to the thickness of the inner front pillar 2 and of the inner side rail 6 outside the reinforced area 16 .
  • An inner upper front pillar reinforcement blank 22 is also provided, for example by cutting the blank 22 from a steel sheet of the same material as the inner front pillar reinforcement blank 20 .
  • the inner upper front pillar reinforcement blank 22 has a contour and dimensions adapted to form the reinforced area 16 when assembled and hot stamped with the inner upper front pillar blank 20 . Consequently, the inner upper front pillar reinforcement blank 22 has a thickness equal to the thickness difference between the thickness of the reinforced area 16 and the thickness of the inner upper front pillar blank 20 .
  • the inner upper front pillar reinforcement blank 22 has therefore a thickness substantially comprised between 0.5 and 1.5 mm.
  • the contour of the inner upper front pillar reinforcement blank 22 is the same as the contour of the part of the inner upper front pillar reinforcement blank 20 where the reinforced area 16 is to extend.
  • the inner upper front pillar reinforcement blank 22 is attached to the inner upper front pillar blank 20 at the location where the reinforced area 16 is to extend, i.e. at an upper end of the inner upper front pillar blank 20 , as shown in FIG. 3 .
  • the inner upper front pillar reinforcement blank 22 is for example spot welded or laser welded to the inner front pillar blank 20 .
  • the obtained assembled blank is then hot stamped to acquire the shape of the inner front pillar 2 and of the inner side rail 6 .
  • an inner center pillar blank 24 is provided.
  • the inner center pillar blank 24 is substantially planar and is for example cut from a steel sheet to have the appropriate contour and dimensions to form the inner center pillar after hot stamping.
  • the steel sheet has a structure consisting essentially of ferrite and perlite arranged such that the inner upper front pillar and side rail will have a structure consisting of 95% or more of martensite after hot stamping.
  • the thickness of the blank 24 is equal to the thickness of the inner center pillar 4 outside the reinforced area 18 .
  • An inner center pillar reinforcement blank 26 is also provided, for example by cutting the blank 26 from a steel sheet of the same material as the inner center pillar reinforcement blank 24 .
  • the inner center pillar reinforcement blank 26 has a contour and dimensions adapted to form the reinforced area 18 when assembled and hot stamped with the inner center pillar blank 24 . Consequently, the inner center pillar reinforcement blank 26 has a thickness equal to the thickness difference between the thickness of the reinforced area 18 and the thickness of the inner center pillar blank 20 .
  • the inner center pillar reinforcement blank 24 has therefore a thickness substantially comprised between 0.5 and 1.5 mm>.
  • the contour of the inner center pillar reinforcement blank 24 is the same as the contour of the part of the inner center pillar reinforcement blank 24 where the reinforced area 18 is to extend.
  • the inner center pillar reinforcement blank 26 is attached to the inner center pillar blank 24 at the location where the reinforced area 18 is to extend, i.e. in a central part of the inner center pillar blank 24 , as shown in FIG. 3 .
  • the inner center pillar reinforcement blank 26 is for example spot welded or laser welded to the inner center pillar blank 24 .
  • the obtained assembled blank is then hot stamped to acquire the shape of the inner center pillar 4 .
  • the inner center pillar 4 is then attached to the inner side rail 6 for example by resistance spot welding or laser welding to form the inner automotive structural part described previously.
  • Attaching the inner front pillar reinforcement blank 22 and the inner center pillar reinforcement blank 26 respectively to the inner front pillar blank 20 and to the inner center pillar blank 24 before the hot stamping steps eases the manipulation of the blanks during said hot stamping steps.
